Outputs
Billable utilisation, non-billable hours and revenue capacity at the entered rate.
Start here
Enter total availability and non-billable time, then compare lower and higher capacity scenarios.
Use a different tool when: Do not use this to set a viable rate and project quote; use Service Rate & Quote Planner for that decision. Use this tool to turn available time into realistic billable capacity.

Billable Utilisation: billable utilisation
Use the billable-time result as a realistic capacity boundary after non-billable work, not as a target for every week.
Formula summary
- Primary formula
- billable utilisation = deliverable hours ÷ gross available hours
Data used here
- The estimate uses your inputs and the general business formula documented in the methodology.
Decision checks
Act on the result
Compare sellable hours with the current pipeline and reserve explicit time for delivery support, sales and administration.
Stress-test the decision
Test more non-billable time or fewer available hours before using the revenue capacity in a hiring or sales plan.
When this estimate can be misleading
- This is a capacity scenario, not a demand forecast or utilisation recommendation.
- All time allocations and rates are your assumptions; no industry benchmark is used.
- It excludes payroll, awards, loaded labour cost, overtime compliance and hiring advice.
- Use the billable-time result as a realistic capacity boundary after non-billable work, not as a target for every week.

Frequently asked questions
How do I turn available time into realistic billable capacity?
Compare sellable hours with the current pipeline and reserve explicit time for delivery support, sales and administration.
What is a good billable utilisation?
This planner does not prescribe one. Test a level consistent with your own admin, sales, leave and delivery work.
Does revenue capacity predict sales?
No. It only multiplies your available billable hours by your entered rate.
Does Margin101 store the time allocation?
